    I have a grease fitting that won't take grease. I did wipe it clean before trying. What do yall do in this situation?

    If it is threaded in the unscrew it and replace with a new one. If it is barbed then wait until the spindle or whatever it is on grenades and replace it.

    Hmmm, Don't you think thats a little silly maniac ? A press in grease fitting can be replaced just as quick if not quicker than a screw in type, All you need is a pair of vise grips to lightly grab the old one and tap with a hammer.
    Install the new one with a 1/4" drive 9/32" socket with a extension to hold it then lightly driven in with a hammer.

    Like I tell my customers with this same complaint, Grease them more often! :hammerhead: of course I mean after you replace the bad ones, the reason they stop taking grease is because the back of the fitting gets packed with dirt, rust, etc. If you are greasing all the fittings as per manufacture specs they are less likely to fail.

    Why not heat it up?

    I found one the other day I didn't know was there. Other than that I do grease them often.

    Thanks for the info guys.

    Because heating one will cause the small spring inside holding the ball in place to shrink then the ball will no longer seal letting dirt into the fitting. Then when greased after that will push the dirt into what ever the fitting is screwed into.

    Try a grease fitting rejuvinator thing. You can put a lighter oil in them and push that through to free things up and then you can grease it and push the oil out.
